Culture methods and matters needing attention of Calyx mandshurica

Growth habits of Calyx calyx

Ornamental pineapple likes warm, humid, sunny environment. Only in bright light can it blossom normally and get the most beautiful leaves, but it is still necessary to prevent direct sunlight at noon in summer. The suitable growth temperature is 20-30 ℃ in summer and 15-18 ℃ in winter. It is difficult to grow when it is lower than 10 ℃, and the lowest at night is 5 ℃. The soil is mixed with rotten leaf soil or peat soil with neutral or slightly acidic sandy loam.

Cultivation techniques of Calyx mandshurica

Media requirement

Cultivation medium for large-scale greenhouse cultivation, because pineapple cultivation takes a long time (from small seedlings to finished large seedlings takes about 2 to 3 years), so the cultivation medium is very important, which directly affects the growth rate and quality of pineapple. Pineapple is a kind of epiphytic plant, and the root growth needs air. Therefore, the cultivation medium must be loose and breathable, good drainage and stable structure. In addition, pineapple likes acidic medium, and its pH value should be kept between 5.5 and 6.5. Generally choose peat soil and perlite to mix at 10:1. The medium must be sealed and disinfected with 100 times formaldehyde solution before use, and the sealing measures must be removed after 15 days, and can only be used after 1 week. At the same time, the interior of the greenhouse must be disinfected two days in advance.

Planting requirement

The seedlings should be planted immediately after delivery, and the planting depth is generally maintained at 1 to 2 centimeters. If it is too deep, the medium will enter into the heart of the seedlings, affecting the growth of the seedlings. In addition, the medium should not be pressed too tightly and keep good permeability as far as possible. Water immediately and thoroughly after planting to ensure a good combination of roots and soil (note: there can be no shortage of water between leaves after planting)

Temperature requirement

The suitable temperature of ornamental pineapple should be between 21 ℃ and 28 ℃ in daytime and from 18 ℃ to 21 ℃ at night. The high temperature should not be higher than 35 ℃ and the low temperature should not be lower than 15 ℃. If the temperature is higher than 35 ℃, it will cause high temperature injury, resulting in slow plant growth, small flower shape and few flower branches. If the temperature is below 10 ℃ for a long time, the leaves and bracts will turn red, white spot, white tip or discoloration, and the diseased part will scorch after drying. If the temperature continues to drop, the plant will die.

In general, the seedlings are relatively young, the temperature should be controlled between 20 ℃ and 25 ℃, and the temperature difference between morning and evening is strictly forbidden. After 3 months of planting, the temperature can be adjusted to between 18 ℃ and 28 ℃, and the temperature difference between day and night should be increased appropriately, which is beneficial to growth. The temperature can be cooled by opening the water curtain or fan system in summer and insulating or heating by using insulation curtain and heating system in winter.

Humidity requirement

Pineapples like a high humidity environment, and the air humidity should be maintained between 75% and 85%. In this humidity range, the plant will become round and plump, and the leaves will shine brightly. When the humidity is too low (less than 50%), the leaves will curl inward or fail to stretch, and even the leaf tip will scorch. However, the humidity should not be too high. If the humidity is too high, brown spots will appear on the leaves of the plant, and in serious cases, the phenomenon of rotten heart will appear. The relative humidity at seedling stage should be controlled between 80% and 85%, and should be controlled between 75% and 85% after 3 months of planting. The air humidity can be increased by sprinkling water under the planting bed and the aisle, and the cooling effect can be achieved at the same time.

Lighting requirement

Light intensity is an important factor that determines plant growth rate, plant shape, flower shape, flower color and so on. The suitable light intensity of pineapple is about 18000 lux. In the suitable range of light, the increase of light intensity will promote the plant leaves to become smaller, the plant shape compact, the flower shape larger and the flower color faster. If the light is too strong, it will leave spots on the leaves and, in severe cases, burn the leaves. If the light is too weak, the plant will grow too long, the color is dark, and the inflorescence is slender and discolored. Generally speaking, the light intensity is controlled at about 15000 lux at the seedling stage. Excessive light will affect the speed of slow seedling. The light intensity can be increased to 20000 to 25000 lux after three months. If the light is too strong, you can use the shading system to shade, and make full use of the light in the morning, evening and cloudy days.

Ventilation requirement

Ventilation is also closely related to the growth of pineapple. Ventilation is not important when the weather is cool, but good ventilation is very important to the plant during the period of high temperature and humidity in summer. When the ventilation is good, the plant is stout, the leaf is wide and thick, the flower ear is large and long, and the flower color is bright; when the ventilation is insufficient, the plant is easy to grow, the leaf is narrow, the flower ear is short, the flower color is not glossy, and it is prone to diseases and insect pests. If necessary, roof windows, side windows and other methods can be used for ventilation.

Moisture requirement

Water quality is very important for ornamental pineapples, and the lower the salt content, the better. The water quality with high calcium and high sodium salt will make the leaves lose their luster, hinder the photosynthesis, and easily cause heart rot and root rot. The EC value should be controlled below 0.3 and the pH value should be between 5.5 and 6.5. When the pH value is higher than 7, it will affect the nutrient absorption of the plant.

The root system of epiphytic ornamental pineapple is weak, it mainly plays the role of fixing plant, and the absorption function is secondary. The nutrition and water needed for its growth and development are mainly stored in the leaf cup formed by the clasping of the leaf base and absorbed by the absorbing scales at the base of the leaf. Even if the root system is damaged or rootless, as long as there is a certain amount of water in the leaf cup, the plant can grow normally. Summer and autumn is the peak growing season of ornamental pineapple, which requires more water, watering the leaf cup once every 4 to 5 days and watering the medium every 15 days or so to keep the leaf cup watery and the medium moist. After entering the dormant period in winter, water the leaf cup once every 2 weeks, the medium is not dry and does not water, the root is too wet and easy to rot.

Fertilizer requirement

Among the three elements of fertilizer nitrogen, phosphorus and potassium, nitrogen can promote leaf elongation and dark green, phosphorus can promote plant transport, while potassium can make leaves shorter and wider and improve leaf quality. Therefore, when preparing fertilizer, the proportion of nitrogen, phosphorus and potassium must be appropriate, which is the prerequisite for cultivating high quality pineapple. The suitable ratio of nitrogen, phosphorus and potassium is 1: 1, 0.5: 1. In addition, pineapples are so sensitive to boron that even small amounts of boron can cause pineapples to burn their tops.

All pineapples need magnesium. Magnesium plays an important role in the synthesis of chlorophyll and enzymes. In the preparation of fertilizer, the best content of magnesium fertilizer is 12%. Pineapple should be fertilized with water, and each watering is accompanied by fertilization. the pH value of fertilizer solution is between 5.5and 6.0. the principle of fertilization is "frequent application of thin fertilizer". In addition, the EC value of fertilizer solution varies with different growth stages. After seedling planting, fertilization can be carried out regularly only when the new root length reaches 2 cm. At this time, the EC value of fertilizer solution should be controlled between 0.5 and 0.8. After 4 months of planting, the EC value was adjusted to about 1.0. When the pineapple changes from the vegetative growth stage to the reproductive growth stage and reaches the flowering state, the EC value should be increased to 1.2. The EC value is still 1.2 after anthesis (note: stop fertilizer for 3 weeks before and after flowering).

Daily management of Miyagi lotus

Change the basin:

It is necessary to change the basin after 4 months of planting. When changing the basin, first put a layer of medium at the bottom of the basin, then take out the pineapple plant from the small basin with soil, put the pineapple plant in the center of the basin, put the medium around it, and gently press it to ensure that the plant is upright. The same medium should not be pressed too tightly to ensure good air permeability. The planting depth should be 3 to 4 cm. Immediately pour clear water after changing the basin, and fertilize it after a month.

Adjust the spacing: after a period of growth, the plant will appear too high density, lack of light, resulting in narrow leaves, growth stagnation, widening the growth gap, therefore, 2 to 3 months after the change of pot, the plant spacing needs to be adjusted.

Grading:

According to the plant size, the plants need to be graded regularly, which is not only beneficial to improve the light of smaller plants, but also conducive to management.

Removal of old leaves: timely removal of old leaves that have no ornamental value, whose bases are yellow and dry.

Prevention and control of calyx disease and insect pest

The diseases of ornamental pineapple can be divided into two categories, one is called non-communicable disease, also known as physiological disease, which is caused by environmental conditions such as light, temperature, water, fertilizer and so on. This kind of disease is more common in pineapple cultivation. The other is called infectious disease, which is caused by infection of microorganisms such as fungi, bacteria, viruses and so on. Notes on the light calyx of Meiye

Calyx calyx generally needs to be changed for about four months, which is more conducive to its growth. in addition, it needs to clean up the yellowed and dried old leaves in time, which can promote its better growth and reduce the waste of nutrients.

Culture method and main value of Calyx mandshurica

Any of several herbs of the family Pterygiaceae having spikelike inflorescences crowded into broad paniculate globose flower heads. Then how to raise the calyx lotus? What is the main value? Let's learn about it next.

1. Culture method of calyx lotus

1. Potted soil: potted plants should mainly choose loose rotten leaf soil or brown peat soil, and add a small amount of river sand and vermiculite to prepare culture soil. When potted, the bottom 1 stroke 4 is filled with granular drainage to facilitate root ventilation and drainage. It is better to keep the pH between 5.5 and 6.5. Generally choose peat soil and perlite to mix at 10:1.

2. Temperature: the suitable temperature of Calyx mandshurica should be between 21 ℃ and 28 ℃ in daytime and from 18 ℃ to 21 ℃ at night, the height should not be higher than 35 ℃ and the low should not be lower than 15 ℃. If the temperature is higher than 35 ℃, it will cause high temperature injury, resulting in slow plant growth, small flower shape and few flower branches. If the temperature is below 10 ℃ for a long time, the leaves and bracts will turn red, white spot, white tip or discoloration, and the diseased part will scorch after drying. If the temperature continues to drop, the plant will die.

3, Illumination: Mei Ye Guang Calyx prefers bright scattered light, avoid strong light direct and too shady. Strong light will burn the leaves of the calyx, while overshade will make the leaves lose luster, and the plant may not blossom. From May to September, shading treatment should be carried out, or pot plants should be placed in a semi-shady place. At other times, giving full light to the calyx can make the plant brighter.

4. Watering: Mei Ye Guang calyx likes to be wet and resistant to drought. Keep the basin soil moist during its growth, and fill the leaf tube with water during watering. During the growth and flowering period of calyx, the leaf tube must be filled with water and keep the water clean. Avoid watering too much. Watering should be controlled at low temperatures in winter, as long as the basin soil is slightly moist. The beautiful leaf calyx likes to be wet, so it should often spray water to the plant and its surrounding environment in its growing season, so as to improve the air humidity.

5. Fertilization: the growing season of calyx lotus is from April to September every year, and liquid fertilizer should be applied once a month at this time. Fertilization is not only applied in the basin soil, but also in the leaf tube and on the leaf surface. Fertilization should be stopped when the winter temperature is below 15 ℃.

6. Pruning and changing pots: after the lotus leaves are faded, the flower branches should be cut off as soon as possible, which can avoid the consumption of nutrients and is conducive to the germination of tillering buds. Young plants should be changed every year.

7. Pest control: when the ventilation is poor, the calyx is prone to shell insects and red spiders, and other diseases and insect pests such as stem rot and whitefly should be prevented and treated.

Second, the main value of the calyx lotus

Mei Ye Guang Calyx lotus pedestal-shaped leaves have tiger-like silver-white stripes and light blue flowers in summer. If you want to blossom ahead of time, put 1-2 ripe apples next to the plant and cover them with a plastic bag. The gas released by the apple can promote flowering. Often make potted plants or hanging pots to watch, beautify the room with it, and decorate the hall is very ideal.

The above is the introduction of the breeding method and main value of the calyx lotus. The calyx lotus can be watched in pots or hanging pots, beautify the room and decorate the hall.

The ecological habit of Calyx mandshurica is sunny and shady; it is suitable for a warm and humid environment and is quite resistant to drought; it requires soil rich in humus, loose and fertile, well drained and breathable. Cultivation techniques of Calyx mandshurica the dragonfly pineapple is a perennial epiphytic herb of the pineapple family. Leaves rosette, wide, curved, gray-green with silver-white stripes, leaf margin spiny. Panicle, tower-shaped, with pink bracts and blue florets. It can be opened for months in a row. Native to tropical and subtropical regions of Central and South America. Not only like the sun, but also afraid of strong direct light. Put the east window indoors, the north window in summer and the south window in winter. The suitable temperature for growth is 16-18 ℃, 50%-60% humidity, and water is sprayed to the plant at high temperature. Use lukewarm soft water, pH4. 1: 4. five. It's best to use Rain Water. The old plant may live for another 6-8 months after flowering, and small plants will grow at the base of the old plant, which can be broken off and planted when the small plant grows to half the size of the mother plant. Two weeks before transplanting, pour some water into the funnel of the small plant, and retain the roots of some old plants as much as possible when transplanting. Leaves and flowers are all beautiful, suitable for potted viewing on several shelves and desks. The propagation mode of Calyx mandshurica can be sowed and tillered. 1. Sowing and propagation: seeds can be easily obtained by artificial pollination after flowering. The seeds are small and need to be sowed by the method of small seeds. Under the condition of 25-30 ℃, seedlings can emerge about one month after sowing. It will grow into flowering plants after about 3-4 years. 2. Tillering reproduction: Calyx lotus blossoms only once in its life. After anthesis, one or more tillering buds will grow at the base of the old plant. When the bud grows to about 10 cm, cut off the mother plant, peel off the lower leaves of the bud, plant after a little air, keep the basin soil moist, and turn to normal management after rooting. The disease control of Calyx mandshurica will produce scale insects when the air is dry and the temperature is high. Fusarium wilt will also occur. It is best to destroy the diseased plants immediately to prevent infection. Indoor cultivation, such as poor ventilation conditions, often harmful to shell insects and thrips, can be sprayed with thin laundry powder or soap solution. Classification of varieties of Calyx chantinii cv. Variegata) the leaves have dark green and white spots, which are very conspicuous. Mosaic dragonfly pineapple (A. fasciata cv. Albo-marinata) there is a longitudinal yellow wide band in the middle of the upper leaf. The distribution area of calyx is native to southeastern Brazil in South America. The pedestal leaves of Calyx calyx have tiger-like silver-white striations and light blue flowers in summer. If you want to blossom ahead of time, put 1-2 ripe apples next to the plant and cover them with a plastic bag. The gas released by the apple can promote flowering. Often make potted plants or hanging pots to watch, beautify the room with it, and decorate the hall is very ideal.
